Description
Overview
GAOTek underground cable fault tester multiple functions safe, quick and accurate test. The instrument applies the methods of Low Voltage Pulse and HV Flashover. It can test all kinds of faults, especially on the Flashover and High Resistance fault testing and without burning through. If it is equipped with a locating instrument, it can exactly point out the location of the fault. High Precision. Our instrument uses the tech of high-speed data sampling, the speed of A or D is 100 MHz, and makes resolution ratio of 3.28 ft (1 m) and testing dead zone of 3.28 ft (1 m). High The testing results automatically show by wave form and data on the large LED. It is easy to view. It does not need especial training for operators.
